].DESCRIPTION AND USES .

Rust-Oleum

Professional Undercoating is an easy to use,

black rubberized protective coating. It provides corrosion

protection from water, salt and other chemicals. It helps

deaden sound and prides a barrier from rust on cars,

trucks, trailers and other recreational vehicles. For use on

bare or primed metal including underbody and wheel wells

of cars, trucks, trailers and other recreational vehicles. Not

for use on surfaces that will come in direct contact with

heat or high temperatures such as mufflers, exhaust

components, etc. Professional Undercoating features an

advanced spray system that allows you to spray at any

angle, even upside down for those hard to reach areas. A

comfort spray tip with a wider finger pad reduces fatigue

caused by continuous spraying.

.PRODUCT APPLICATION .

PAINTING CONDITIONS

Use outdoors or in a well-ventilated area such as an open

garage. Apply when temperature is between 50-90°F (10-

32°C) and humidity is below 85% to ensure proper drying.

Avoid spraying in very windy, dusty conditions. Cover

surrounding area to protect from spray mist.

SURFACE PREPARATION

Bare Metal or Sound Rust Surfaces: Remove all dirt,

grease, oil, salt and chemical contaminants by washing

the surface with a commercial detergent, or other suitable

cleaning method. Rinse with fresh water and allow to

thoroughly dry. Remove loose paint and rust with a wire

brush or 120-220 grit sandpaper. Remove all sanding dust

with a clean cloth. Protect and mask off all surrounding

areas to prevent overspray. For best results, spot prime

bare or rusted surfaces.

Previously Painted Surfaces: Thoroughly clean the area

with a commercial detergent, or other suitable cleaning

method. Rinse with fresh water and allow to thoroughly

dry. Note: Cleaning is recommended before and after wire

brushing or sanding. Use a wire brush to remove any

loose or peeling paint. Sand the surface with 120-220 grit

sandpaper. The use of 249321 Primer Sealer or any of the

sandable primers (249419 Red, 252472Light Gray, or

249415 Gray) will enhance corrosion resistance and

improve hiding.
